New pathway to valleytronics
A potential avenue to quantum computing currently generating quite the buzz in the high-tech industry is "valleytronics," in which information is coded based on the wavelike motion of electrons moving through ...
Students most effectively math working on problems that they enjoy, not drills or exercises
Students learn math best when they approach the subject as something they enjoy, according to a Stanford education expert. Speed pressure, timed testing and blind memorization pose high hurdles in the youthful ...
Cryptographic algorithm can prevent unwanted sharing of personal data, including credit card numbers
IBM researchers today announced plans for a cloud-based technology that holds potential to help consumers better protect online personal data, including date of birth, home address and credit card numbers.
US settles case against 'revenge porn' site operator
A man accused of operating a "revenge porn" website has settled with U.S. regulators who said he broke the law by posting nude pictures of women without their consent or knowledge.
New largest number factored on a quantum device is 56,153
Mathematicians trace source of Rogers-Ramanujan identities, find algebraic gold
Mathematicians have found a framework for the celebrated Rogers-Ramanujan identities and their arithmetic properties, solving another long-standing mystery stemming from the work of Indian math genius Srinivasa Ramanujan.
Researchers crack unassailable encryption algorithm in two hours
(Phys.org) —A protocol based on "discrete logarithms", deemed as one of the candidates for the Internet's future security systems, was decrypted by EPFL researchers. Allegedly tamper-proof, it could only ...
Experiment opens the door to multi-party quantum communication (Update)
In the world of quantum science, Alice and Bob have been talking to one another for years. Charlie joined the conversation a few years ago, but now by enforcing the space-like separation of the three parties, ...
The ABC's of animal speech: Not so random after all
The calls of many animals, from whales to wolves, might contain more language-like structure than previously thought, according to study that raises new questions about the evolutionary origins of human language.
Autonomous robots: A self-organizing thousand-robot swarm (w/ Video)

Virtual currency "Riecoin" uses computations to help solve math problem
Calculating encryption schemes' theoretical security guarantees eases comparison, improvement
Most modern cryptographic schemes rely on computational complexity for their security. In principle, they can be cracked, but that would take a prohibitively long time, even with enormous computational resources.
